Abstract
A method for generating an entry includes a first network device that receives a first advertisement packet, where the first advertisement packet includes a source autonomous system (AS) identifier, and the source AS identifier corresponds to a source device of the first advertisement packet; and the first network device that generates a forwarding entry based on the source AS identifier, where the forwarding entry includes an identifier of a first egress, and the first network device receives the first advertisement packet through the first egress.
Claims20
A first network device comprising:
- a receiver configured to receive a first advertisement packet through a first egress, wherein the first advertisement packet comprises a source autonomous system (AS) identifier, and wherein the source AS identifier identifies a source device of the first advertisement packet;
- and
- a processor coupled to the receiver and configured to generate a forwarding entry comprising the source AS identifier and a first identifier of the first egress.
A first network device comprising:
- a receiver configured to obtain a first packet comprising a destination address, wherein the destination address comprises a destination autonomous system (AS) identifier, and wherein the destination AS identifier identifies a destination device of the first packet;
- a processor coupled to the receiver and configured to determine a first egress based on the destination AS identifier;
- and
- a transmitter coupled to the processor and configured to send the first packet to the destination device through the first egress.
A network system comprising:
- a first network device configured to:
- receive a first advertisement packet through a first egress, wherein the first advertisement packet comprises a source autonomous system (AS) identifier, and wherein the source AS identifier identifies a source device of the first advertisement packet;
- and
- generate, based on the source AS identifier, a forwarding entry comprising the source AS identifier and a first identifier of the first egress;
- and
- a second network device coupled to the first network device and configured to:
- generate the first advertisement packet;
- and
- send the first advertisement packet to the first network device.
